Advanced Log Parser Charts Part 1 - Working With Configuration Scripts

I recently had a situation where I wanted to customize the chart output from Log Parser, and after a bunch of research I eventually arrived at the conclusion that configuration scripts to create customized charts are probably the least-documented feature of Log Parser. After a lot of experimentation, (and a bit of frustration), I finally managed to achieve the results that I wanted. With that in mind, I thought that it would make a great blog series if I documented some of the settings that I used.

Log Parser and Chart Configuration Scripts

When you look in the Log Parser help file, it makes mention of using configuration scripts to customize charts, and it provides the following small JavaScript sample:

// Add a caption
chartSpace.HasChartSpaceTitle = true;
chartSpace.ChartSpaceTitle.Caption = "Generated by Log Parser 2.2";
chartSpace.ChartSpaceTitle.Font.Size = 6;
chartSpace.ChartSpaceTitle.Position = chartSpace.Constants.chTitlePositionBottom;

// Change the background color
chart.PlotArea.Interior.Color = chartSpace.Constants.chColorNone;

Unfortunately, this sample isn't very useful, although I found dozens of forum posts that quote this sample as a way to do things - but it's the only sample that most people cite. The Log Parser help file mentions looking at the MSDN ChartSpace Object Model documentation, but that documentation is only slightly more useful. These two references are what led me to my earlier conclusion that chart configuration scripts are not well-documented, and especially when you are trying to do something with Log Parser.

What I found to be particularly helpful was to use the Log Parser COM interface and write scripts by using Adersoft's VbsEdit and JsEdit. In case you haven't used either of those applications, they are great IDEs for writing scripts; they both give you a great debugging environment, and they have a great object browser that I used to discover what options were available to me. In the end, these two editors made it possible to create the chart configuration scripts that I will discuss in this blog series.

By the way, chart configuration scripts can be written in VBScript or JavaScript, but for this blog I will use VBScript for the Log Parser COM samples and JavaScript for the configuration script samples. I didn't have to do it that way, but it seemed like a good idea to help differentiate between the samples.

Using COM versus the Command-Line

For the samples in this blog series, I will use Log Parser's COM interface and VBScript to create my charts, but this is not necessary; everything that I am documenting can be done from the command-line version of Log parser, and I'll give you some quick examples to see the differences.

The following examples generate some simple area charts that plot the total number of hits by day, and both examples do exactly the same thing:

Command-Line:

logparser.exe "SELECT Date, COUNT(*) AS Hits INTO HitsByDay.gif FROM *.log GROUP BY Date ORDER BY Date" -i:W3C -fileType:GIF -groupSize:800x600 -chartType:Area -categories:ON -values:ON -legend:OFF

COM Interface:
Option Explicit

Dim objLogQuery, strSQL
Dim objInputW3CFormat, objOutputChartFormat

Set objLogQuery = WScript.CreateObject("MSUtil.LogQuery")
Set objInputW3CFormat = WScript.CreateObject("MSUtil.LogQuery.W3CInputFormat")
Set objOutputChartFormat = WScript.CreateObject("MSUtil.LogQuery.ChartOutputFormat")

strSQL = "SELECT Date, COUNT(*) AS Hits " & _
" INTO HitsByDay.gif " & _
" FROM *.log " & _
" GROUP BY Date " & _
" ORDER BY Date"

objOutputChartFormat.groupSize = "800x600"
objOutputChartFormat.fileType = "GIF"
objOutputChartFormat.chartType = "Area"
objOutputChartFormat.categories = "ON"
objOutputChartFormat.values = "ON"
objOutputChartFormat.legend = "OFF"

objLogQuery.ExecuteBatch strSQL, objInputW3CFormat, objOutputChartFormat
Ugly Charts

Using some of the log files from one of my websites, the above samples created the following basic chart:

Taking a look at this chart makes it easy to see why you would want to customize your output; that light blue is pretty awful, and those values are pretty hard to read.

Specifying Configuration Scripts

If you remember the incredibly basic configuration script from earlier, you only need to add one parameter to each example in order to specify the configuration script:

Command-Line:

logparser.exe "SELECT Date, COUNT(*) AS Hits INTO HitsByDay.gif FROM *.log GROUP BY Date ORDER BY Date" -i:W3C -fileType:GIF -groupSize:800x600 -chartType:Area -categories:ON -values:ON -legend:OFF -config:HitsByDay.js

COM Interface:
Option Explicit

Dim objLogQuery, strSQL
Dim objInputW3CFormat, objOutputChartFormat

Set objLogQuery = WScript.CreateObject("MSUtil.LogQuery")
Set objInputW3CFormat = WScript.CreateObject("MSUtil.LogQuery.W3CInputFormat")
Set objOutputChartFormat = WScript.CreateObject("MSUtil.LogQuery.ChartOutputFormat")

strSQL = "SELECT Date, COUNT(*) AS Hits " & _
" INTO HitsByDay.gif " & _
" FROM *.log " & _
" GROUP BY Date " & _
" ORDER BY Date"

objOutputChartFormat.groupSize = "800x600"
objOutputChartFormat.fileType = "GIF"
objOutputChartFormat.chartType = "Area"
objOutputChartFormat.categories = "ON"
objOutputChartFormat.values = "ON"
objOutputChartFormat.legend = "OFF"
objOutputChartFormat.config = "HitsByDay.js"

objLogQuery.ExecuteBatch strSQL, objInputW3CFormat, objOutputChartFormat
Simple Output

Taking a look at the resulting chart, you can see why I mentioned earlier that the configuration script wasn't very useful; all it does is add a centered title to the bottom of the chart:

Yup - that's a pretty useless sample configuration script for chart customization.

Next...

In my subsequent posts, I'll show how to make this chart (and several other types of charts) look a lot better.

How to create an HTML Application to configure your WebDAV Redirector settings

I've mentioned in previous blog posts that I use the Windows WebDAV Redirector a lot. (And believe me, I use it a lot.) Having said that, there are a lot of registry settings that control how the Windows WebDAV Redirector operates, and I tend to tweak those settings fairly often.

I documented all of those registry settings in my Using the WebDAV Redirector walkthrough, but unfortunately there isn't a built-in interface for managing the settings. With that in mind, I decided to write my own user interface.

I knew that it would be pretty simple to create a basic Windows Form application that does everything, but my trouble is that I would want to share the code in a blog, and the steps create a Windows application are probably more than I would want to write in such a short space. So I decided to reach into my scripting past and create an HTML Application for Windows that configures all of the Windows WebDAV Redirector settings.

It should be noted, like everything else these days, that this code is provided as-is. ;-]

Using the HTML Application

When you run the application, it will present you with the following user interface, which allows you to configure most of the useful Windows WebDAV Redirector settings:

Creating the HTML Application

To create this HTML Application, save the following HTMLA code as "WebDAV Redirector Settings.hta" to your computer, and then double-click its icon to run the application.

<html>

<head>
<title>WebDAV Redirector Settings</title>

  APPLICATIONNAME="WebDAV Redirector Settings"
  ID="WebDAV Redirector Settings"
  VERSION="1.0"
  BORDER="dialog"
  BORDERSTYLE="static"
  INNERBORDER="no"
  SYSMENU="no"
  MAXIMIZEBUTTON="no"
  MINIMIZEBUTTON="no"
  SCROLL="no"
  SCROLLFLAT="yes"
  SINGLEINSTANCE="yes"
  CONTEXTMENU="no"

Additional Notes

You will need to run this HTML Application as an administrator in order to save the settings and restart the Windows WebDAV Redirector. (Which is listed as the "WebClient" service in your Administrative Tools.)

This HTML Application performs basic validation for the numeric fields, and it prevents you from exiting the application when you have unsaved changes, but apart from that there's not much functionality other than setting and retrieving the registry values. How else can you get away with posting an application in a blog with only 500 lines of code and no compilation required? ;-]

How to add <clear/> or <remove/> Elements through Scripting

I had a question recently where someone was trying to add <clear /> or <remove /> elements to a collection in their IIS 7 configuration settings. With that in mind, for today's blog I thought that I would discuss a couple of ways to add <clear /> and <remove /> elements by using two specific scripting methods: AppCmd and VBScript.

It should be noted that you can also use JavaScript or PowerShell, but I'm not covering those because the syntax for those is available elsewhere. (JavaScript syntax is available in the Configuration Editor in IIS Manager, and the PowerShell syntax is available through the Web Server (IIS) Administration Cmdlet Reference.) You can also use Managed-Code, and the syntax for that is also available in the Configuration Editor in IIS Manager; but compiled code isn't scripting, is it? :-)

Here's the scenario, IIS makes it possible to modify the contents of an inherited collection in two ways:

  • You can clear the contents of an inherited configuration section, as illustrated by the following configuration excerpt:
    <configuration>
       <system.webServer>
          <defaultDocument enabled="true">
             <files>
                <clear />
             </files>
          </defaultDocument>
       </system.webServer>
    </configuration>
  • You can remove an item from an inherited collection, as illustrated by the following configuration excerpt:
    <configuration>
       <system.webServer>
          <defaultDocument enabled="true">
             <files>
                <remove value="index.html" />
             </files>
          </defaultDocument>
       </system.webServer>
    </configuration>

With that in mind, let's look at scripting those settings.

Using AppCmd

AppCmd.exe is a great utility that ships with IIS 7, which allows editing the configuration settings for IIS from a command line. This also allows you to create batch scripts that automate large numbers of configuration changes. For example, the following batch file enables ASP session state, sets the maximum number of ASP sessions to 1000, and then sets the session time-out to 10 minutes for the Default Web Site:

appcmd.exe set config "Default Web Site" -section:system.webServer/asp /session.allowSessionState:"True" /commit:apphost

appcmd.exe set config "Default Web Site" -section:system.webServer/asp /session.max:"1000" /commit:apphost

appcmd.exe set config "Default Web Site" -section:system.webServer/asp

I'm a big fan of IIS 7's AppCmd.exe, but unfortunately it has two rather large limitations:

  • AppCmd.exe does not directly support clearing the contents of a configuration section. (But there's a workaround that I list below.)
  • AppCmd.exe does not support removing an item from a collection.

These limitations have caused me some grief from time to time, because I often want to script the modification of collections, and I would love to remove items or clear a collection.

How to add a <clear /> element using AppCmd:

Although it's kind of a hack, there is a way to force AppCmd.exe to add a <clear /> element.

Here's what you need to do in order to clear the list of default documents for the Default Web Site:

  1. Create an XML file like the following and save it as "CLEAR.XML":
    <?xml version="1.0" encoding="UTF-8"?>
    <appcmd>
        <CONFIG CONFIG.SECTION="system.webServer/defaultDocument" path="MACHINE/WEBROOT/APPHOST" overrideMode="Allow" locked="false">
            <system.webServer-defaultDocument  enabled="true">
                <files>
                    <clear />
                </files>
            </system.webServer-defaultDocument>
        </CONFIG>
    </appcmd>
  2. Run the following command:
    appcmd.exe set config /in "Default Web Site" < CLEAR.xml

Unfortunately this technique does not work for <remove /> elements. :-( But that being said, you can add a <remove /> element through VBScript; for more information, see the Using VBScript section.

Using VBScript

Fortunately, VBScript doesn't have AppCmd.exe's limitations, so you can add both <clear /> and <remove /> elements.

How to add a <clear /> element in VBScript:

The following steps will clear the list of default documents for the Default Web Site:

  1. Save the following VBScript code as "clear.vbs":
    Set adminManager = WScript.CreateObject("Microsoft.ApplicationHost.WritableAdminManager")
    adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST/Default Web Site"
    Set defaultDocumentSection = adminManager.GetAdminSection("system.webServer/defaultDocument", _
      "MACHINE/WEBROOT/APPHOST/Default Web Site")
    Set filesCollection = defaultDocumentSection.ChildElements.Item("files").Collection
    filesCollection.Clear
    adminManager.CommitChanges
  2. Run the VBscript code by double-clicking the "clear.vbs" file.

How to add a <remove /> element in VBScript:

The following steps will remove a single item from the list of default documents for the Default Web Site:

  1. Save the following VBScript code as "remove.vbs":
    Set adminManager = WScript.CreateObject("Microsoft.ApplicationHost.WritableAdminManager")
    adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST/Default Web Site"
    Set defaultDocumentSection = adminManager.GetAdminSection("system.webServer/defaultDocument", _
      "MACHINE/WEBROOT/APPHOST/Default Web Site")
    Set filesCollection = defaultDocumentSection.ChildElements.Item("files").Collection
    addElementPos = FindElement(filesCollection, "add", Array("value", "index.html"))
    If (addElementPos = -1) Then
       WScript.Echo "Element not found!"
       WScript.Quit
    End If
    filesCollection.DeleteElement(addElementPos)
    adminManager.CommitChanges
    
    Function FindElement(collection, elementTagName, valuesToMatch)
       For i = 0 To CInt(collection.Count) - 1
          Set element = collection.Item(i)
          If element.Name = elementTagName Then
             matches = True
             For iVal = 0 To UBound(valuesToMatch) Step 2
                Set property = element.GetPropertyByName(valuesToMatch(iVal))
                value = property.Value
                If Not IsNull(value) Then
                   value = CStr(value)
                End If
                If Not value = CStr(valuesToMatch(iVal + 1)) Then
                   matches = False
                   Exit For
                End If
             Next
             If matches Then
                Exit For
             End If
          End If
       Next
       If matches Then
          FindElement = i
       Else
          FindElement = -1
       End If
    End Function
  2. Run the VBscript code by double-clicking the "remove.vbs" file.

Viewing current FTP7 sessions using VBScript

A few weeks ago my friend Jaroslav posted a blog entry about viewing the current FTP7 sessions using Javascript, and I followed that up with a blog post about viewing the current FTP7 sessions using C#.

This blog entry follows up on those postings by showing you how to view the current FTP7 sessions using VBScript. To do so, copy the following VBScript code to Windows Notepad and save the file as "ftp_sessions.vbs" on a computer running Windows Server 2008 with the new FTP7 server installed:

Option Explicit

Dim objAdminManager, objSiteCollection, objFtpSiteElement
Dim objSite, objFtpSession, objFtpSessions, objFtpProperty
Dim intSite, intFtpSession, intFtpProperty
Dim intSiteCount, intFtpSessionCount, intFtpPropertyCount

Set objAdminManager = WScript.CreateObject("Microsoft.ApplicationHost.AdminManager")

' get the collection of sites
Set objSiteCollection = objAdminManager.GetAdminSection( _
  "system.applicationHost/sites", "MACHINE/WEBROOT/APPHOST" )

intSiteCount = CInt(objSiteCollection.Collection.Count)

WScript.Echo String(40,"*")
WScript.Echo "Site count: " & intSiteCount
WScript.Echo String(40,"*")

' loop through the sites collection
For intSite = 0 To intSiteCount-1

  ' get a site
  Set objSite = objSiteCollection.Collection.Item(intSite)
  
  ' get the FTP section
  Set objFtpSiteElement = objSite.ChildElements.Item("ftpServer")
  
  ' get the sessions collection
  Set objFtpSessions = objFtpSiteElement.ChildElements.Item("sessions")
  intFtpSessionCount = CInt(objFtpSessions.Collection.Count)

  WScript.Echo String(40,"=")
  WScript.Echo "FTP sessions for " & _
    objSite.Properties.Item("name").Value & _
    ": " & intFtpSessionCount
  WScript.Echo String(40,"=")

  ' loop through the sessions
  For intFtpSession = 0 To intFtpSessionCount - 1
    Set objFtpSession = objFtpSessions.Collection.Item(intFtpSession)
    intFtpPropertyCount = CInt(objFtpSession.Properties.Count)
    ' loop through each session's properties
    For intFtpProperty = 0 To intFtpPropertyCount - 1
      Set objFtpProperty = objFtpSession.Properties.Item(intFtpProperty)
      WScript.Echo CStr(objFtpProperty.Name) & ": " & CStr(objFtpProperty.Value)
    Next
    WScript.Echo String(40,"-")
  Next
Next

To make sure that you don't see any message box pop-ups, run the script from the command-line using the following syntax:

cscript.exe ftp_sessions.vbs

That's about it for this post - have fun!

IIS 6: Creating an Itemized List of Server Bindings

One of my servers has a large number of individual web sites on it, and each of these web sites has several server bindings for different IP addresses, Port Assignments, and Host Headers. As I continue to add more web sites on the server, it becomes increasingly difficult to keep track of all the details using the IIS user interface.

With that in mind, I wrote the following ADSI script which creates a text file that contains an itemized list of all server bindings on a server.

Option Explicit
On Error Resume Next

Dim objBaseNode, objChildNode
Dim objBindings, intBindings
Dim objFSO, objFile, strOutput

' get a base object
Set objBaseNode = GetObject("IIS://LOCALHOST/W3SVC")
Set objFSO = WScript.CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.CreateTextFile("ServerBindings.txt")

' check if if have an error ...
If (Err.Number <> 0) Then

    ' ... and output the error.
    strOutput = "Error " & Hex(Err.Number) & "("
    strOutput = strOutput & Err.Description & ") occurred."

' ... otherwise, continue processing.
Else
    ' loop through the child nodes
    For Each objChildNode In objBaseNode
        ' is this node for a web site?
        If objChildNode.class = "IIsWebServer" Then
            ' get the name of the node
            strOutput = strOutput & "LM/W3SVC/" & _
                objChildNode.Name
            ' get the server comment
            strOutput = strOutput & " (" & _
                objChildNode.ServerComment & ")" & vbCrLf
            ' get the bindings
            objBindings = objChildNode.ServerBindings
            ' loop through the bindings
            For intBindings = 0 To UBound(objBindings)
                strOutput = strOutput & vbTab & _
                    Chr(34) & objBindings(intBindings) & _
                    Chr(34) & vbCrLf
            Next
        End If
    ' try not to be a CPU hog
    Wscript.Sleep 10
    Next
End If

objFile.Write strOutput
objFile.Close

Set objBaseNode = Nothing
Set objFSO = Nothing

Hope this helps!

Updating several IP addresses using ADSI

(Note: I had originally posted this information on a blog that I kept on http://weblogs.asp.net, but it makes more sense to post it here. [:)] )

Like many web programmers, I host several hobby web sites for fun. (They make a wonderful test bed for new code. ;-] )

And like many computer enthusiasts, I sometimes change my ISP for one reason or another. If you are hosting web sites in a similar situation, I’m sure that you can identify the pain of trying to manually update each old IP address to your new IP address. This situation can be made even more difficult when any number of your web sites are using several host headers because the user interface for the IIS administration tool only lists the first host header. This means that you have to manually view the properties for every site just to locate the IP addresses that you are required to change.

Well, I'm a big believer in replacing any repetitive task with code when it is possible, and a recent change of ISP provided just the right level of inspiration for me to write a simple Active Directory Service Interfaces (ADSI) script that locates IP addresses that have to be changed and updates them to their new values.

To use the example script, I would first suggest that you make a backup copy of your metabase. (The script works fine, but it is always better to have a backup. ;-] ) As soon as your metabase has been backed up, copy the example script into notepad or some other text editor, update the old and new IP addresses that are defined as constants, and then run the script.

Option Explicit
On Error Resume Next
 
Dim objIIS
Dim objSite
Dim varBindings
Dim intBindings
Dim blnChanged
 
Const strOldIP = "10.0.0.1"
Const strNewIP = "192.168.0.1"
 
Set objIIS = GetObject("IIS://LOCALHOST/W3SVC")
 
If (Err <> 0) Then
  WScript.Echo "Error " & Hex(Err.Number) & "(" & _
    Err.Description & ") occurred."
  WScript.Quit
Else
  For Each objSite In objIIS
    blnChanged = False
    If objSite.class = "IIsWebServer" Then
      varBindings = objSite.ServerBindings
      For intBindings = 0 To UBound(varBindings)
        If InStr(varBindings(intBindings),strOldIP) Then
          blnChanged = True
          varBindings(intBindings) = Replace(varBindings(intBindings),strOldIP,strNewIP)
        End If
      Next
    End If
    If blnChanged = True Then
      objSite.ServerBindings = varBindings      
      objSite.Setinfo
    End If
  Next
End If
MsgBox "Finished!"

That’s all for now. Happy coding!
